/**
* Legacy version of {@link java.util.function.Supplier java.util.function.Supplier}. Semantically,

*
* The {@link Suppliers} class provides common suppliers and related utilities.
*
*
As this interface extends {@code java.util.function.Supplier}, an instance of this type can be
* used as a {@code java.util.function.Supplier} directly. To use a {@code
* java.util.function.Supplier} in a context where a {@code org.docx4j.com.google.common.base.Supplier} is
* needed, use {@code supplier::get}.
*
*
See the Guava User Guide article on the use of {@code Function}.
